Sheet Overlap Control in Laminating Systems During Image Interruptions
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing laminating systems face challenges in maintaining consistent sheet overlap during image forming operations, particularly when temporary interruptions occur, leading to adhesive contact with conveyance rollers and potential damage to the system.
Innovation Solution
The system includes a mechanism to overlap and reduce the interval between sheets to prevent gaps between laminating and a hardware processor to determine and change the execution timing of specific processing to ensure stable overlap and reduce the interval between sheets, and a hardware processor to determine whether or not specific processing occurs in a job, and changes the execution timing of specific processing to ensure stable overlap and reduce the interval between sheets, and a hardware processor to determine whether or not to determine the timing of specific processing, and a laminator to prevent adhesive contact with the conveyance of the system.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If the image forming apparatus executes specific processing (such as correction operation) to maintain image quality, then the image quality is improved, but the interval between successively conveyed sheets becomes non-constant, causing unstable sheet overlap and potential adhesive contact with conveyance rollers
Solution Approach 1:
The control unit determines in advance whether specific processing will occur during the job by checking job information. When specific processing is detected, the control unit adjusts the execution timing of that processing to occur before or after the job, rather than during. This preliminary determination and timing adjustment prevents the interval between sheets from becoming non-constant, thereby maintaining stable sheet overlap and preventing adhesive contact with conveyance rollers while still allowing the specific processing to be executed to maintain image quality
2Reliability
If the laminating apparatus continuously conveys sheets with constant interval, then the lamination processing is stable, but the adhesive may contact conveyance rollers when sheets are not properly overlapped due to large distances between sheets
Solution Approach 1:
The control unit continuously monitors job information to determine whether specific processing occurs. Based on this feedback, the control unit dynamically adjusts the execution timing of specific processing to prevent large intervals between sheets. This feedback mechanism ensures that sheets are continuously conveyed with appropriate overlap, preventing adhesive from contacting conveyance rollers while maintaining stable lamination processing

AI summary
A laminating system including: a laminator that performs lamination processing on a plurality of sheets that are conveyed; a second sheet conveyor that is on an upstream side of the laminator and that overlaps a leading end and a trailing end of respective sheets among the plurality of sheets conveyed from a first sheet conveyor including an image former or reduces an interval between the sheets so as not to generate a gap between the sheets; and a hardware processor that determines whether or not specific processing operated by temporarily interrupting an image forming operation occurs in a job, and changes an execution timing of the specific processing to a timing before a start or after an end of the job in response to determination that the specific processing occurs.
